6.1

ACCESSING LRUs

The G1000 mounting system is designed to simplify the installation, removal, and servicing of G1000
LRUs. The system typically consists of a main system rack, LRU racks, a Cable Harness Protection
System (CHiPS) harness assembly, and any required cooling accessories or other structural supports
mounted behind the instrument panel. Typically, the PFD and MFD mount to the instrument panel cutout
directly in front of the main system rack. In this way, LRUs are quickly accessible by removing and
disconnecting the display. Refer to the installation and outline drawings in each LRU installation manual
for detailed installation/removal information.
Before removing any LRU, verify the LRU software part number and version against the software
configuration listed in the Required Equipment List.
To check an LRU software part number and/or version:
1. Start the G1000 system in configuration mode.
2. The System Status Page (Figure 6-1) shows a list of LRUs in the LRU window. Activate the cursor
and use the FMS knob to scroll through the list in the window and select the displayed LRUs.
3. The software part number and version is displayed in the DATA window. Compare this to the
software configuration in the Required Equipment List.
4. If a faulty LRU is not reporting its software version and part number, check aircraft maintenance logs
for last software version loaded and verify against the Required Equipment List. The Software
Manifest Page can also be used to check part numbers and versions.
